Several recent arxiv articles like
http://arxiv.org/abs/1409.6290/
reviewing the pbr theorem
http://arxiv.org/abs/1111.3328/
got me thinking about this again with respect to
straightforward two-slit interference, which I'd
thought simply and unambiguously resolved the issue
in favor of "it's real". And that resolution goes
back to (and likely before) Feynman's general audience
lectures

You can perform a two-slit electron interference experiment,
and slowly reduce the luminosity/intensity of the source until
it's so low that you're virtually guaranteed that only one
electron at a time passes through the slits. And then accumulated
counts at the scintillation screen still exhibit interference.
So doesn't that simply mean the wavefunction/quantum_state is
ontologically "real"? If it just represented epistemic ensemble
statistics, there wouldn't be any self-interference from a
low-luminosity source.
That argument seems pretty obvious, so I guess it must be flawed, or I'd imagine it would be widely used.
So what's wrong with it?
